Selection and installation

Check stroke, energy per cycle and hourly energy together with impact speed, cycle rate, driving force and available installation space. Use external adjustment to match the application; confirm the contact accessory and mounting thread for this model.

Series working principle

The piston forces oil through metering passages to dissipate impact energy. Turning the adjustment knob changes the effective flow area; the return mechanism resets the piston after the load is removed.

Catalog application and mounting notes

EKL42X50 is an industrial shock absorber with a 50 mm stroke and an M42 × 1.5 mounting thread. The approved product record specifies an operating velocity range of 0.08–1.30 m/s. The EKD catalog provides the model dimensions alongside the EK42 and EK64 family. Check both energy per cycle and hourly energy against the actual moving mass, drive force and cycle rate. Confirm the mounting dimensions, usable travel, stop position and return clearance for the machine before ordering; do not substitute standard EK velocity ratings for this EKL model.

Engineering limits to confirm for this model

Published data below describes the model. A missing value needs confirmation; it is never a passed check. Use the cited model drawing and operating conditions when requesting a review.

Temperature ranges are series catalog references. Confirm the fluid, seals and ordered configuration; an optional range is not a standard-model rating.

Questions before ordering

Is an EKD candidate a confirmed drop-in replacement?
No. A candidate needs separate dimensional and application checks. Provide the complete original code, drawing, moving mass, impact speed, drive force, cycle rate and environment. Missing operating limits require written engineering confirmation before approval.
Are price, lead time and warranty the same for every model?
No universal price, dispatch time or warranty duration is established here. Request a written offer for the exact configuration, accessories, quantity and destination, including sample availability, minimum order, shipping, applicable warranty and failure-resolution terms.
